The Stainless Steel 135 Degree Corner Handrail Bracket is a specialized post-top saddle component designed to connect and support continuous handrails at a fixed $135^\circ$ angle. Engineered for modular architectural balustrades, this angled stem bracket allows handrail runs to navigate wide turns, octagonal landings, and angled staircase transitions smoothly without requiring complex field welding or custom miter fabrication.
Featuring a solid ∅ 14 mm cylindrical support stem, this fitting provides a standard vertical clearance height (H) of 80 mm measured from the base collar to the underside of the handrail plate. The upper fixed 135 ° top plate includes pre-drilled countersunk holes and is available in a flat profile or curved saddle curvatures (∅) designed to fit 33.7 mm, 42.4 mm, and 48.3 mm round handrail tubes. The lower base adapter sleeve (D) press-fits directly into standard vertical post tubes measuring 33.7 mm, 42.4 mm, or 48.3 mm outer diameter. Precision-machined from high-grade stainless steel options—AISI 304, AISI 316, and Duplex SS 2205—and offered in brushed satin (matte) or mirror-polished (shiny) finishes, these modular railing fittings provide continuous support across professional handrail support systems.

Q1: What is the primary function of a 135 Degree Corner Handrail Bracket?
A: A 135 Degree Corner Handrail Bracket mounts onto vertical post tops to support and guide continuous handrails around wide 135 ° turns, eliminating the need for complex on-site miter cutting or welding.
Q2: What handrail and post sizes fit this corner bracket?
A: Both the upper saddle curvature (∅) and lower post sleeve (D) accommodate standard round tube outer diameters of 33.7 mm, 42.4 mm, and 48.3 mm (with flat saddle options available for wooden or rectangular handrails).
Q3: What clearance height does this bracket provide between the post top and handrail?
A: This fitting provides a fixed vertical clearance height (H) of 80 mm from the lower post sleeve to the base of the handrail saddle.
Q4: Which material grade should be selected for outdoor or coastal applications?
A: Choose AISI 316 or Duplex SS 2205 stainless steel for outdoor, coastal, or severe marine environments to ensure maximum protection against chloride pitting, salt spray, and oxidation.
